//Q/w/Mf/m UNITED STATES To all whom it may concern Be it known that I, LEWIS A. FoLsoM, of Dalton, in the county of Whitfield and State of Georgia, have invented anew and lmproved Automatic Fire-Extinguishcr, of which the following is a specification.

The drawing represents a vertical sectional central elevation ofthe device.

The object of this invention is to provide a simple and eflicient apparatus for extinguishing lires.

The invention consists of two barrels or other vessels, set one within the other, the outer one containing sulphuric or other acid, and the inner one carbonate of soda or other alkaline carbonate, into which latter vessel a third vessel, containing gunpowder or other explosive, is introduced, saidgexplosive vessel having a fuse or tube filled with powder connected with it and extending upward through the cover of the other vessels, so that lire applied to the said tube or fuse will be communicated tothe explosive in theinteror vessel, and cause an explosion which will-burst asunder the containing-vessels, and thereby cause theircontents to mingle, by which means a suicient volume of carbonic-acid gas will be generated to extinguish the lire.

In the drawing,Arepresents the outer barrel or vessel for containing the acid, preferably sulphuric acid. B is a smaller vessel for holding the alkali, preferably bicarbonate of soda. O is the interior vessel for holding the gunpowder or other explosive, and D is the fuse or tube communicating with the said vessel C and passing upward out of the cover E of the device.

rEhe apparatus charged as described may be placed in any room where a re is. likely to occur.

vPowder and other combustible material is placed upon the top of the cover E, so that it may be quickly ignited on the breaking out of PATENT OFFICE.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 228,621, dated June 8, 1880` Application filed January 14, 1880.

the iire, and when the combustible lnaterial on the cover of the vessel is ignited the fire communicates at once, through the tube or fuse D, with the powder in the vessel O and causes an explosion, which will instantly shatter both containing-vessels A and B, and mix and throw the acid and alkaliin every direction about the room, thus forming carbonic-acid gas in suflicient quantity to extinguish any iire at once.

The device is especially designed for cottongin houses, where tire may occur at any inoment from friction of machinery, 85o., and where a tire would burn so rapidly' that it would be practically impossible to supply water fast enough to extinguish. it soon enough to save any ofthe contents of the building, or indeed, the building itself. I would place this apparatus, charged as above set forth, near the ceiling of the lint-room in a gin-house, so that should a fire break out it would instantly communicate to the fuse and explode the ap. paratus. y

Should this device be placed for use in a dwelling-house, and should the house take iire, some one might proceed at once to the room or closet containing the device and set lire to the fuse with a match or candle, and then retire, when soon the explosion would occur that would supply enough carbonic-acid gas to put out the re in the house.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- Afire-extinguishing apparatus consisting of the acid, carbonate, and explosive vessels A B C, respectively, set one within another, and provided with cover E and tube D, substantially as and for the purpose described.
